[jira] [Created] (DRILL-2538) Project's setupNewSchema() does not create the correct schema with children

----------------------------------

             Summary: Project's setupNewSchema() does not create the correct schema with children
                 Key: DRILL-2538
                 URL: https://issues.apache.org/jira/browse/DRILL-2538
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Mehant Baid


While creating the schema for the outgoing batch in project (setupNewSchema()) we don't create the child vectors for the complex vectors. We create the children only while performing the transfer in doWork(). This is ok for most cases, but if we have a blocking operator before project and  our first batch is a schema batch with no records then the transfer would not create the child vectors and we would propagate half baked schema downstream.
